Definitions

  • the present invention relates to a needle cap covering a needle of an injector, a guide for needle cap and a grip for needle cap each fitted on the needle cap.
  • a needle cap covering a needle of a disposable injector is, for example, shown in FIG. 9.
  • a needle cap 51 has a shape of a bottomed tube with the rear end (right end in the FIG. 9) thereof opened.
  • a user catches the needle cap 51 with fingers F of one hand while keeping hold of an injector A with the other hand not shown. Then the user positions the opening 52 of the needle cap 51 in relation to a needle N of the injector A, and puts the needle cap 81 on the needle N.
  • An object of the present invention is to provide a needle cap, a guide for needle cap and a grip for needle cap which eliminate any fear that a finger of a user taking the needle cap should touch the tip of a needle by accident when the user puts the needle cap on the needle.
  • the needle cap of the present invention comprises a cylindrical cap body having an opening at its longitudinal end and covering a needle; and a gripped portion provided on the cap body to extend substantially in the radial direction of the cap body.
  • FIG. 1 is a schematic view showing a state in which a needle cap of a first embodiment of the present invention is covering a needle of an injector;
  • FIG. 2 is a front view of FIG. 1;
  • FIG. 3 is a schematic view showing a state in which the needle cap has covered the needle of the injector
  • FIG. 4 is a schematic view showing a modification of a needle cap
  • FIG. 5 is an exploded schematic view showing a guide for needle cap
  • FIG. 6 is a schematic view showing a grip for needle cap
  • FIGS. 7 and 8 are schematic views respectively showing modifications of guides for needle cap.
  • FIG. 9 is a front view showing a needle cap of the related art.
  • a first embodiment of the present invention which is embodied in a needle cap adapted to cover a needle of a disposable injector, will be explained hereunder in accordance with FIGS. 1 to 3.
  • an injector A to which the needle cap of the present embodiment is fitted, comprises a piston and a cylinder which slidably accommodates the cylinder 1.
  • a supporting member 3 provided with a needle N is attached to a leading end (left end in FIG. 2) of the cylinder 2.
  • the needle cap made of, for example, a synthetic resin is put on the supporting member 3.
  • a cylindrical cap member 4, which constitutes a main part of the needle cap, has a bottom at its front end and an opening at its rear end, and defines therein an accommodating recess which is able to accommodate the needle N.
  • a fitted portion 6 is formed at the rear end of the cap body 4 and has a larger thickness than the cap body 4.
  • the fitting portion 6 has an inner diameter substantially as large as that of the outer diameter of the supporting member 3 so as to be fittable onto the same supporting member 3.
  • a guiding portion 8 having a semicircular section is integrally formed on the lower half part of the fitting portion 6 so as to protrude rearwardly therefrom so that the opening 8 of the cap body 4 is able to be positioned in relation to the needle N by getting an inner surface 8a of the guiding portion 8 in contact with one side of the needle N.
  • a thin plate like gripped portion 9 extends from the outer periphery of the cap body 4 in the radial direction thereof so that the user can grip the portion 9.
  • the cap body 4, guiding portion 8 and gripped portion 9 constitute the needle cap.
  • FIGS. 1 and 2 respectively show a state in which the needle cap is covering the needle N of the injector A after injection.
  • the user grips the gripped portion 9 with the fingers F of one hand while holding the injector A with the other hand. Then the user brings the needle cap close to the needle N and positions the opening 5 to the needle N.
  • the guiding portion 8 of semicircular section is formed at the opening 5, the user can easily position the opening 5 to the needle N by putting the inner surface 8a of the guiding portion 8 on the leading end portion of the needle N, so that there is no fear that the finger F should touch the needle N.
  • the user moves the needle cap toward the supporting member 3 of the injector A while holding the gripped portion, and puts the fitting portion 6 of the needle cap on the supporting portion 3 of the injector A as shown in FIG. 3, thereby to cover the needle N by the needle cap.
  • the fingers F holding the gripped portion 9 are away from the opening 8, since the gripped portion 9 is formed on the cap body 4 such as to extend in the radial direction thereof. Therefore, even in case the opening 5 has not been exactly positioned in relation to the needle N, it is never apprehended that the finger F should touch the needle N.
  • the needle cap of the present embodiment even if pathogene of a patient have adhered to the needle N in injection, there is no possibility that the user should catch the disease of the patient, so that there arises no sanitary problem, contrary to the needle cap of the related art.
  • a guiding portion 18 and a gripped portion 19 may be made of a leaf composed of a sheet of paper, synthetic resin, etc., and be adhered to the needle cap body 14 via adhesive agent, adhesive double coated tape and so on.
  • the present invention may be embodied into a guide for needle cap fittable to a needle cap body 24, for example as shown in FIG. 5.
  • the same guide comprises a cylindrical connecting portion 30 fittable to the needle cap body 24, and a gripped portion 29 and a guide portion 28 each formed integrally with the connecting portion 30.
  • the guide for needle cap has similar effects to those of the above mentioned embodiment.
  • the present invention may be embodied into a grip for needle cap fittable to a needle cap body 34, for example as shown in FIG. 6.
  • the same grip comprises a cylindrical connecting portion 40 fittable to the needle cap body 34 and a gripped portion 39 integrally formed with the connecting portion 40.
  • the present invention may be embodied into a needle cap consisting of the guide portion 8 without provision of any gripped portion, for example as shown in FIG. 7.
  • the guide portion 8 may be formed separately from the cap body 4 so as to be detachable to the cap body 4.
  • an adhesive tape may be adhered on the outer periphery of the fitting portion 6 and then have the upper part thereof removed so as to form a guide portion 48.
